There is a popular theory that suggests a connection between the Giza Pyramids and the Orion constellation. The theory is based on the alignment of the three main pyramids at Giza with the three stars that form the "belt" of the Orion constellation. The three pyramids of Giza were built during the Old Kingdom period of ancient Egypt, around 4,500 years ago. The Great Pyramid, the largest of the three, was built for Pharaoh Khufu and is believed to have been completed around 2560 BCE. The Orion constellation was very important in ancient Egyptian mythology and was associated with the god Osiris, who was believed to have been reborn as a star in the constellation. The alignment of the pyramids with the stars of Orion's belt has led some to suggest that the ancient Egyptians intentionally designed the pyramids to mirror the stars in the sky. There are several arguments for and against this theory, and it remains a topic of debate among scholars and re...

  The Andromeda galaxy is one of the most fascinating and awe-inspiring celestial objects in the universe. Located approximately 2.5 million light-years from Earth, it is the closest spiral galaxy to our own Milky Way. The Andromeda galaxy is named after the mythological Greek princess Andromeda, and is also known as M31 or NGC 224. The Andromeda galaxy is an incredibly large and complex system, with an estimated mass of over one trillion stars. It has a diameter of around 220,000 light-years, making it roughly twice the size of the Milky Way. It is also home to many fascinating and unusual features, such as a massive central bulge, a prominent ring of gas and dust, and numerous satellite galaxies. One of the most intriguing aspects of the Andromeda galaxy is its collision course with our own Milky Way. Scientists believe that the two galaxies will collide in around 4 billion years, creating a massive new galaxy known as Milkomeda. While the collision itself is unlikely...

spacenews: 4 साल से लंबा ना हो एक अभियान, जानिए ऐसा क्यों कह रहे हैं शोधकर्ता जिस तरह दुनिया के कई देशों की स्पेस एजेंसियां मंगल ग्रह (Mars) पर मानव (Humans) भेजने की तैयारी और शोध कर रही हैं, उससे नहीं लगता कि यह संभव नहीं हैं. अरबों खबरों डॉलर मंगल ग्रह पर मानव के रहने लायक हालात बनाने और उससे संबंधित शोध पर खर्च किए जा रहे हैं. मंगल यात्रियों (Mars Travellers) को वहां भेजने के लिए अभी हमारे वैज्ञानिकों और इंजीनियरों को बहुत से तकनीकी और सुरक्षा चुनौतियों से निपटना है. हाल ही में अंतरराष्ट्रीय शोधकर्ताओं की एक टीम ने निष्कर्ष निकाला है कि मंगल पर मानव अभियान (Human Missions) तभी ठीक रह सकता है यदि वह चार साल से ज्यादा लंबा ना हो. विकिरण की बड़ी चुनौतियां मंगल यात्रा के दौरान  इंसानों के सामने सबसे बड़ी चुनौतियों में से एक वहां पर आने वाले सूर्य, दूर के तारों और गैलेक्सी से आने वाले महीन कणों विकरण का सामना करने की होगी. ऐसे में दो सवाल अहम हैं. क्या यह विकिरण इंसानों के लिए पूरी यात्रा के दौरान खतरा बना रहेगा और क्या अभियान की समयावधि उन्हें इन विकिरणों से बचा सकती है...
